A plication fil d July 20,1905. Serial No. 270.513.

To (LZZ whom it may concern.-

Be it known that I, JosEPH J. BRIN, a citi- Zen of the United States, residing at Chicago, in the county of Cook, State of Illinois, have invented certain new and useful Improvements in Syringes, of which the following is a specification.

My invention relates to that class of syringes wherein there is used an expanding and contracting frame whereby the walls of the vagina or other parts may be dilated to facilitate the treatment thereof; and my invention consists, chiefly, in the novel means and manner of expanding and contracting said frame.

There are certain well-known objections to syringes of this type, such as the pinching of the tissue membrane or the like when the frame is contracted and the difficulty of operating the same withoutdisturbing the position of the syringe when once set. In my invention I avoid these inconveniences and provide a 'syringe of simple, economical, and durable construction by which there can be no pinchingor tearing of the tissues, and means are provided for adjusting the same without disturbing its position.

To these ends my invention consists, chiefly, in the provision of an expanding device of novel form in combination with any suitable form of bulb member to cooperate therewith.

In the drawings, Figure 1 is a side elevation with parts broken away and other parts in section. Fig. 2 is a detail view of the cone. Fig. 3 is an elevation, partly in section, of a modified form of my invention. Fig. 4 is a detail view of the cap for the cone. Fig. 5 is a detail plan view of the cone with the cap removed, and Fig. 6 is a cross-sectional view on line 6 6 of Fig. 2.

Referring to the drawings, 1 represents a bulb of any desired form having a cap or collar 2, connected to a discharge-pipe or spraytube 3 in any desired manner, two methods being shown at 4 and 5.

6 is a sliding tube fitting over the dischargepipe and carrying an air-cushion member 7, having apertures 8 for the purpose of the ingress and egress of air and supported at its base by the plate 9,which in turn is supported by the ring 10, secured to the sliding tube 'by means of the screw 11, the top portion of said cushion member fitting closely around. the upper end of the sliding tube, as shown at 12. To the sliding tube there is attached the cone 13 or other suitable head by means of the rod 14:, secured to the sliding tube and cone by any suitable means, as shown at 15 and 16. 17 is a cap secured to the end of the cone by means of the screw 18. The walls of the cone are preferably, and as herein shown, inwardly convergent, providing surfaces of different angles and said surfaces having connectingslots 21 and 22 therein.

23 represents fingers constituting an expanding frame or dilator, which fingers are of any desired form, preferably flat on their upper faces and secured to the discharge-pipe or spray-tube, as shown at 24, and carrying lugs 25 and 26, adapted to fit within and without said cone, said lugs traveling on either side of the slots to securely retain the fingers therein, the outside lugs being beveled at 27 and at substantially the same angle as the beveled surface 20. In the preferred mode of operation one hand of the operator engages the cushion 7while the other engages the bulb member 1. Then by a forward movement of the bulb member the spray-tube and dilator are advanced, forcing the lugs to move up the inclined surfaces of the cone in the slots or tracks and distending the fingers. In contracting my device the operation is reversed and the fingers in their downward and inward course move constantly away from the tissue down the slots of the cone until the lowest point of the bevel is reached when the contraction becomes complete. It is evident that by the downward and inward movement of said finger-dilators the tissue slides free from the fingers and cone, as they lie practically in the same plane when the fingers are in a contracted position, thus rendering the pinching or lacerating of the tissues impossible.

A feature not heretofore explained, but which is regarded as important, is that the finger members project beyond the end of the cone, thus allowing a free flow of liquid around the end of the cone. It. is also to be noted that as the bearing-surfaces of the lugs (shown at 27) are on the same angle as the surface 20 of the cone the finger members shaped head serves the function of a guard to prevent the tissue or membrane from becoming pinched or 'lacerated between the fingers in the contracting movement of the latter, since it serves to hold the membrane or tissue away from the fingers during the con IIO tracting movement. It will also be observed that the fingers are expanded by and during the act or movement of applying the instrument and, conversely, are retracted by the act or movement of withdrawing the same, thus accomplishing the double function by a single movement of the instrument.

It is obvious that various changesin my invention may be made without departing from the spirit of the same, such as converting it into a fountain-syringe by attaching to the spray-tube a hose having a suitable bulb attachment and providing the spray-tube with l a disk having radially-disposed apertures, as

shown at 28, to produce a spray in place of a solid stream, or the bar 14- may be in the form of a tube having apertures connected to a perforated cone.

Having fully described my invention, what I claim, and desire to secure by Letters Patent, is-

1. In asyringe the combination with aspraytube of aseries ofdistending-fingers surrounding said tube and means for distending said fingers comprising a head to which the outer ends of said fingers are slidably connected and means for imparting a relative sliding movement to said cone and linger members, substantially as described.

2. In asyringe the combination with aspraytube,of a series ofdistending-fingers surrounding said spray-tube, a beveled head to which the outer ends of said fingers are slidably connected and means for imparting a relative sliding movement to said head and finger members, substantially as described.

3. In a syringe the combination with aspraytube, of an expansible frame, a beveled head having tracks within it, the frame being slidably connected to said tracks whereby the ends of the frame will lie concealed within said head when in a contracted positi n, and means for imparting a relative sliding movement to said head and frame,substantially as described.

4. In asyringe the combination with aspraytube having fingers attached thereto, of a sleeve sliding upon said tube, a beveled cone attached to said sleeve, grooves within said cone to which the fingers are slidably connected, and

means fonimparting a relative sliding movement to said cone and finger members, substantially as described.

5. In a syringe the combination with aspraytube of a series of distending-fingers, a sleeve sliding upon said spray-tube and provided with a cushion, a slotted cone attached to said sleeve, to which the outer ends of said fingers are slidably connected and means for imparting a relative sliding movement to said cone and finger members, substantially as described.

6. In asyringe the combination with aspray tube,ofaseriesofdistending-fingers surrounding said tube, means fordistending said fingers comprising a cone to which the outer ends of said fingers are slidably attached and project beyond the end of the cone, and means for imparting a relative movement to said cone and finger members, substantially as described.

7. In a syringe, the combination with a spraytube,ofaseries ofdistending-fingers surrounding said tube, and means for distending said fingers comprising a head to which the outer ends of said fingers are slidably connected, said head beingof a form and size to serve as a guard for the ends of said fingers, and means for imparting a relative sliding movement to said head and fingers, substantially as described.

8. In a syringe,the com bination with a spray- Y JOSEPH J. BRIN.
